M series indirect oil or gas fired mobile heaters

Output range from 22kW to 173kW

M Range Indirect Oil or Gas Warm Air Heater
Efficient, reliable and applicable anywhere essential for heat distribution with hoses.

Due to the high-power radial fans fitted to this range of mobile heaters, these units are especially suitable for heat distribution with warm air hoses. This ensures efficient heating from outside the building ,warehouse ,marquees,etc that is being heated

The optional re-circulating air module allows an even more efficient and economical operation.

The integral fuel tank and the heating cartridge feature on the M25 and M50 make these models independent, space-saving and immediately ready for use.

The models M70 to M200 have a fuel supply pipe to be connected to an external tank and a preheated filter which makes them also immediately ready for use. Quality-brand oil burners and silent, yet powerful fans convert more than 93 % of the energy into heat.
